I've wanted to get back into abstracts lately but I was stuck. Nothing seemed to work. I broke down and bought a book by Rolina van Vliet called "Painting Abstracts: Ideas, Projects and Techniques." Generally I'm cheap -- by spending $$ on a book I effectively forced myself to try some new abstracts. (FWIW, the same technique, in this case paying for 3 months at the gym, seems to be working!) Both are acrylic on 12 x 16 canvas board.
